MY IP shows wrong

[zoby]

When i go to www.whatismyip.com it show:

213.239.***.234

Earlier it was:

85.221.***.239

What happened? I've never seen any IP that start with 213 before, thanks in advance.

btw: Earlier I maanged to host websites and Ventrilo, now I can't

Hi Zoby,

Your ISP could be growing and adding new IP blocks for its users.

It's very possible for the blocks to be that far apart as well. 81.x.x.x vs. 213.x.x.x and assigned to the same ISP to dole out to their users.

Try refresh the page or reload the page (ctrl shift refresh/reload]

Guys

I know this is kind of technical - but here's some Perl code to convert ip addresses to names, and vice versa. It's called 'hosty.pl'

#!/usr/bin/perl -w

use Socket;

my $host = shift or die "hosty <address>\n" ;

if ( $host =~m/([0-9]+\.[0-9]+\.[0-9]+\.[0-9]+)/) {
  $address = inet_aton($host) ;
  $A = gethostbyaddr($address,AF_INET) ;
} else {
  $address = gethostbyname($host) ;
  $A       = inet_ntoa($address)  ;
}

print "$host = $A\n" ;

So it goes like this (my IP address at the moment is 69.3.28.41):

C:\>hosty 69.3.28.41
69.3.28.41 = h-69-3-28-41.snvacaid.dynamic.covad.net

C:\>hosty h-69-3-28-41.snvacaid.dynamic.covad.net
h-69-3-28-41.snvacaid.dynamic.covad.net = 69.3.28.41

C:\>

I've never bothered to monitor this, however I'm sure covad.net have many blocks of IP addresses.

Unix affectionados probably know the 'whois' command which reveals lots of stuff about an IP address:

I'm sure there's a similar command in Windows, but off-hand I can't think what it's called. If you google for whois, you'll find web sites where you can type in an IP address and they'll display the same information as above.

Anyway, if you find your IP address changing significantly, use hosty nn.nn.nn.nn to find out the DNS name of the server. And of course, unless there's something very strange in the wires, you'll find you're ISP's DNS name is consistent.
